The longer hiking trails at the Island generally begin on the mesa top and descend via switchbacks to the White Rim bench. A few trails continue down to one of the rivers. Most are considered strenuous, with an elevation change of 1,000-2,000 feet, and require negotiating steep slopes of loose rock as well as sections of deep sand. Water is scarce in most areas. Trails are marked with cairns (small rock piles).
Elevation: 5,520 ft.
Length: 20 mi/32 km round-trip
Start: Alcove Spring Trailhead
Trail descends via steep switchbacks to a rocky wash that leads into this broad, steep-walled canyon. Hikers can follow the four-wheel-drive road to the Green River. Four at-large camping permits are available. Groups may encounter significant traffic on the roads as well as on the river. Returning to the trailhead via Upheaval Canyon reduces the round-trip mileage.
